Specification of Letters Patent.

Application filed April 20, 1906. Serial No. 312.932.

T0 all whom it 17a/ay concern:

Be it known that I, JACOB ROEDIGER, a citizen of the United States,residing in the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Sand-Delivery Boxes forRailway-Cars, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

My invention relates toV a box for delivering sand from a suitablereceptacle to the rails of railway-tracks, the box being constructed toprovide for the reception of the sand and the discharge of the sandtherefrom under the action of an air-currentdelivered into the box.

Figure I is a perspective view of my sanddelivery box. Fig. II is anenlarged longitudinal section taken through the box'. Fig. III is atransverse section taken on irregular line III III, Fig. II. Fig. IV isa perspective view of the side plate of the box looking at the innerside thereof.

1 designates the main member of my box, which has one closed side wall,two closed end walls, and a top, in the latter of which is an inlet 2,located near one end of the box, through which the sand to be deliveredfrom the box is received. In one of the end walls of the member1-namely, the wall adjacent to the inlet 2-is a jet-duct 3, and securedto said end wall is an air-conducting pipe 4, through which air isconveyed to the box to be discharged thereinto through the jetduct 3.

5 is an outlet-spout leading from the lower side of the main box memberat the end opposite that at which the sand-inlet opening 2 and theair-duct 3 are located. This outlet-spout is adapted to have attached toit a tube or chute through which the sand is conveyed to the point atwhich it is to be discharged onto the railway-track rail.

6 designates a side plate or side wall member by which the side of themain box member which is not occupied by a wall is closed. This. sideplate is provided upon its inner face with a rim 7, that is adapted toseat within the main box member at its open side, and it also bears atits inner side a guard 8 and a deflector 9, both of which parts areintegral with said side plate. The deiiector 9 bears at its terminationa threaded stem 10,

which is adapted to pass through the closed side wall of the box member1 and which receives a nut 11, (see Fig. III,') by which the side wall 6is held to the main box member. The guard 8 is located in a verticalposition within the chamber of the delivery-box and immediately in frontof the sand-inlet opening 2 in the top ofthe box, and said guard extendsdownwardly from the top of the box to a point sufficiently remote fromthe bottom of the box to provide a passage-way leading from thesand-inlet opening into the main portion of the box-chamber. Thedeiiect-or 9 is located considerably in advance of the guard 8 andextends upwardly from the bottom of the box to a point remote from thetop of the box in order that a passage-way may be provided thereoverinto the portion of the box-chamber from which the sand is delivered tothe outlet-spout 5. The main member 1 of the box is surmounted by aplate 12, that is provided with a neck 13, which contains a verticalopening that registers with the sand-inlet opening 2. The neck 13 isadapted to be connected to the receptacle in which the sand is carried,and the sand pasess therethrough to enter the chamber of thedelivery-box.

14 is a slide-valve that is loosely iitted between the top of the mainmember of the delivery-box and the top plate 12 at the end of the box atwhich the sand-inlet opening 2 and the neck 13 are located. Thisslide-valve is provided with an aperture 15, that is adapted to bebrought into registration with the openings 2 and 13 to permit flow ofsand into the chamber of the delivery-box wall. The portion of saidvalve that is not occupied by said aperture is adapted to serve as aguard for preventing the ow of sand when the aperture 15 is out ofregistration with the openings 2 and 13. The slide-valve may be actuatedin any desirable manner. When the sand enters into the chamber of mydeliverybox through the inlet-openings 2, it moves downwardly into thebox-chamber between the end wall adjacent to said inlet-aperture and theguard 8 facing said end wall at the opposite side of the inlet-aperture,and as the sand enters a portion of the chamber beneath said guard it ismet by a blast of air entering the box-chamber through the duct 3 fromthe air-conducting pipe 4 and driven forwardly toward the defiector 9.The deflector 9 be- IOO IOS

ing located between the points of inlet ofthe I' sand and air and thespout 5, the sand is prevented rom taking a direct course through thebox-chamber to the outlet-spout and is directed upwardly by saiddelector toward the top of the box to pass over the deflector in an evenstream before entering the outletspout. It will be readily understoodthat in the ow of the sand under air-blast in the upward course over thedeilector there is a constant tendency toward the creation of an eddy inthe boxchamber, which causes the sand to circle rearwardly toward thesandinlet opening 2 but the entrance of the sand so directed into theinlet-opening is prevented by the guard 8, which, as previously stated,is located immediately in advance of the inlet-opening.

By providing the valve 14 I am enabled to shut off the liow of sand intothe deliverybox whenever the sand becomes clogged therein in order thatthe ingress of sand into said box may be prevented during the cleaningoperation. In accomplishing such cleaning operation it is only necessaryto remove the side plate 6 of the box after removing thev nut ll appliedto the threaded stem 10, which is carried by said side plate and passesthrough the side wall of the main member of the delivery-box. When saidside plate is removed, the clogged sand in the box is readily dislodgedfrom the box-chamber, and the side plate is then again replaced, theentire cleaning operation requiring but a short period of time and anextremely small amount oflabor.

I claiml A sand-delivery box consisting of a hollow main member having asand-inlet, an air-inlet and a sandoutlet, and a detachable side platehaving a delector and a guard integral therewith whereby said last-namedmembers may both be withdrawn from said main member when said side plateis removed, substantially as set forth.
